Abstract:
A high voltage power supply includes a frequency signal generation unit, a voltage generation unit, and a voltage amplifying unit. The frequency signal generation unit generates a frequency signal. The voltage generation unit generates an input voltage according to the frequency signal generated by the frequency signal generation unit. The voltage amplifying unit amplifies and outputs the input voltage by rectifying and smoothing the input voltage a plurality of times. A voltage output by the voltage amplifying unit is changed by changing a frequency of the frequency signal.
